FP-50-M piston vibrator with stainless steel, easy to install, long service life. FP-50-M piston vibrator is the use of high-pressure compressor through the air inlet into the product piston chamber. Push the piston up, the piston cavity gas is squeezed through the exhaust hole. When the piston up to the end, the gas through the tank and the airway automatically change the gas into the piston chamber. The high pressure gas pressure piston down to the end of the first cycle of the end of the second cycle, followed by continuous reciprocating cycle so that the oscillator generated translational and shaking, resulting in vibration.
